Anplicetion filed July 5, 1918.

State of Pennsylvania, have invented a new and Improved Ernergeney-Brnke, of which the following is a full, clear, and exact de scription. v

This inyention relates to a brake device especially adapted for Ford cars, and it has for its general objects to provide a substitute brake construction "whereby the brake band Will engage externally the brake drum so as to secure greater reliability and holding power, there being :1 novel supporting means which is npglied to the stationary disk associated with the brake drum for holding the brake band and the toggle device for contracting the brake benn into frictional engagement with the drum.

Still another object of the invention is to provide simple, novel and effective means for holding the brake hand normally out of engagement with the drum at all points.

With such and other objects in View, the invention comprises various novel feat of construction and arrangement of parts which will be setiorth with particularity in the following description and claims appended hereto in the accompanying drawing, which illustrates one embodiment. of the invention and where similar characters of reference indicate. corresponding parts in both the 'iews,

each of which is provided with e slot 15 through which extends apin 16. The inner end of the pin is attached to the brake band 5, and on the pin is a spring 1? bearing against an abutment 18 formed by a Washer, whereby the spring tends to urge the pin outwardly away from the axle, so that the brake band is normally held at a plurality of spaced goints away from the brake dram.

The central portion of the supporting member 6 has an outwardly extending lug 19 which carries a pivot 20- on which is fulornlnecg an operating lever 21, and around this pivot is fastened the eye 22 on one end of the brake hand, whereby sneh held against movement. The opposite end 23 of the brake band is g rovided witl ear 24. having an epertnre engaging this aperture is an edjnstnhl enutmen the form of a nut 25 threaded on a toggle member 27. The member is pivotconnecte-cl 28 the other toe e member formed by the arm lever 21. The not serves es en ed connection for lens toggle link so as to vii of the brake bend serves to prevent the ti 2? from wearing.

The lever-21 will be connected with t emergency operating lever which, when in off position, will hol tle free ends of brake bend disengaged from the drum, when the operating" lever 's actuated the ends of the e bands are drawn by the toggle device 2?, springs 1? Will permit the brake bend to more in weirdly, end consequently 1 gripped uniformly operating lever .1s will automatically drum.
